An Arrest Warrant in Las Vegas, Nevada is signed and issued by a local judge or magistrate when a member of the arresting agency (any local police department or government agency), signs a declaration of arrest affidavit, where that officer swears under oath that all information provided in that document is true, and the issuing judge after careful review finds that the officer has detailed sufficient probable cause for your arrest. Now what does all that mean in laymen’s terms? Let’s say, Nicole enters a Neiman Marcus department store and steals a designer Louis Vuitton purse worth $2,500. Security has her on camera but she leaves the store before she can be detained. Security then contacts the Las Vegas Metropolitan Police Department and files a report. Officer Owens recognizes Nicole from the tape, he then writes up a declaration for arrest affidavit, which states he is in possession of a security tape from the store which clearly shows Nicole stealing the purse. Officer Owens then signs and presents this to the judge swearing under oath that all information in the declaration is true. The Judge then determines that the security video establishes probable cause that Nicole did in fact commit the crime of Burglary and Grand Larceny, and then signs the arrest warrant.  With the Arrest Warrant in hand Officer Owens has legal authority to find Nicole, arrest her, and place her in custody.
